Started a bit late due to setting up the thread and monitoring the leaderboard to open it up but still got it decently quick for having barely touched rust
Probably able to get it down shorter so might revisit it
Oh, doing this is Rust is really simple.
I tried doing the same thing in Rust, but ended up doing it in Python instead.
Ive been trying to learn rust for like a month now and I figured Iβd try aoc with rust instead of typescript. Your solution is way better than mine and also pretty incomprehensible to me lol. I suck at rust -_-
he used one letter variable names, it's very incomprehensible.
Get yourself thru the book and you'll get everything here.
Yeah tried to golf it a bit so its not very readable
Seems like the site doesn't track characters though so won't do that for future days
It basically just loops through every character on a line, if it's a number it sets last to that and if its not a number it checks if theres a substring starting on that point that equals one of the 10 strings that are numbers
In case that this might help.
h.chars() returns an iterator of characters. Then he concatenate chars and see if it's a digit or a number string.
You can swap match u.is_numeric() with if u.is_numeric and covert _ => branch to else.
